29# Variation of crossmp3.sh. fifos and sockets added to load.
30# Not really a cross mount point test, but a test of the old
31# non-directory use of the vnode v_un union.
32# mckusick@ suggested using fifos for this test.

34# "panic: mtx_lock() of spin mutex  @ ../kern/vfs_subr.c:512" seen.
35# https://people.freebsd.org/~pho/stress/log/crossmp8.txt
36# Fixed by r291671.
